How we scored this 100 out of 100
| Signal | Finding | Points |
|---|---|---|
| SHA-256 hash published | 9 of 9 installers ship a SHA-256 hashWithout a published hash there is no way to prove the file you downloaded is the file the publisher built. | 30 / 30 |
| Binary provenance | 9 on the publisher's own domainThe strongest signal against a repackaged installer: the file should come from the publisher, not from a mirror nobody vouches for. | 35 / 35 |
| Served over HTTPS | 9 of 9 over HTTPSAn installer fetched over plain HTTP can be modified in transit. | 15 / 15 |
| Release recency | last release about 4 months agoSoftware that has not shipped in years accumulates unpatched vulnerabilities. | 15 / 15 |
| Licence declared | GPL-3.0A declared licence tells you what you are actually allowed to do with the software. | 5 / 5 |
